Abstract

This paper is focusing on IMS session continuity of a Mobile Node (MN) roaming from different access technologies. Comparison between different mobility solutions used in NGNs are addressed. Vertical mobility using End-User context information and SIP signaling are foreseen to efficiently comply to 3GPP standards and to provide enhanced end-user satisfaction. The usage of SIP mobility within our solution does not introduce any change in the signaling functionalities nor the architecture. Only slight modifications are required in the P-(or I-)CSCF in order to enable media switching. This paper also introduces a new algorithm in the MN to handle incoming media from different network interfaces. A proof-of-concept involving wlan to 3G mobility validates our analysis and provide interesting results.
